May 12, 1936. c. o. MARX PORTABLE COLD BEER DISPENSER Filed Feb. 13, 1935 LLLJ \NVENTOR CHARLES OMARX BY W %ORNEY Patented May 12, 1936 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to new and useful improvements in a portable cold beer and beverage dispenser.

The invention relates to a device provided with a plug engageable in the bung hole in the top of a beer barrel or other beverage keg, and associated with a vertical pipe extending through the plug for engaging into the beverage, and connected with a cooling coil, and mechanism for the discharge of air into the barrel to provide pressure for the dispensing of the beverage. Combinations of this type are generally known, this invention applying to novel features in the combination.

The invention has for an object the construction of an article as mentioned which is characterized by the fact that the plug is of hollow construction and slidably and adjustably arranged upon the vertical pipe and associated in such a manner with an air supplying mechanism that adjustments of the position of the plug on the pipe are possible without interfering with the operation of the device. The feature of this arrangement is that the apparatus may readily be adjusted to barrels of different heights.

A further object of this invention is to construct the device in such a manner that an air pump operated with a vertical stroke of a handle is arranged coaxially with said vertical pipe so as 39 to be in a firmly supported position. In prior constructions the hand pumps were ofiset and connected with the coils of the device or in other positions in which they were not rigidly supported which did not produce a compact solid unit as taught by this invention.

A further object of this invention is the association of a container for ice or other refrigerant, with the coil previously mentioned, and the construction of the parts in such a manner that the hand pump is located centrally of the container.

Still further the invention proposes the construction of an article as mentioned which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-

Fig 3 is an: elevational view looking in the direction of the line 33 of Fig. 1.

The portable cold beer and beverage dispenser,

according to this invention, comprises a vertical pipe II] for extension into the beer II of a beer barrel I2 (illustrated fragmentarily). A cooling and dispensing device is supported on the top of the vertical pipe III and is connected therewith. This cooling and dispensing device comprises a container I3 open at the top and equipped with a coil I4 arranged in such a manner that a refrigerant may be placed therein to cool liquid in the coil.

' The coil I4 has a discharge end I la connected with a faucet I5 mounted on the outer side of the container. The coil I4 has an inlet end Mb connected with a pipe I6 arranged through the bottom of the container and connecting with a brackat I! attached upon the bottom of the container axially therewith. The bracket I! is formed with a hollow portion I8 which is cut off from the pipe I6. The pipe I6 opens into a receiving portion Ilia. having an opening at the bottom connecting with the upper end of the pipe I0. The pipe I!) extends into the bottom of the bracket I1 and is secured with a rubber gasket I9 arranged in a recess in the bracket I1 and clamped into tight position with a gland arranged coaxially upon the pipe I6 and threadedly engaging the outer end of the recess.

An air pump 2! is attached on the cooling and dispensing apparatus and is connected with the hollow portion I8 of the bracket H. The details of this pump will not be given since pumps of this type are generally known and form no part of this invention. To better understand the operation of the device it is stated that the pump 2| is provided with a handle 22 on the top which may be moved vertically upwards and downwards to operate the pump. The pump has air inlets 23 at the top and a discharge 24 which extends through the bottom of the receptacle I3 and connects with the hollow portion I8. The bracket I1 is provided with an outlet 25 from the hollow portion I8.

A hollow plug 26 for engaging through the bung opening 21 of the beer barrel I2 is arranged coaxially on and adjustably fixed with the pipe I ID. More particularly, the pipe IIJ extends through a packing gasket 21 arranged in the top end of the plug and clamped into compressed condition with a plug 28 threadedly engaged in the recess in which the packing is disposed. The

hollow portion 29 of the plug surrounds the pipe I!) and discharges at the lower end of the plug completely around the pipe. The hollow portion 29 connects with a side inlet 30. A detachable hose 3! is engaged upon the outlet and the inlet 30 to connect these parts.

The pipe 10 is formed from a lower pipe section Illa and an upper pipe section lllb connection together with a valve body 32 provided with a cock type of valve 33. The valve 33 controls the passage of the beer or beverage through the pipe ID. The bottom of the receptacle I3 is provided with an outlet 34 for the discharge of. water or liquid in the event that the refrigerant is of the type that melts, such as ice.

The operation of the device is as follows: The plug 26 is adjusted upon the pipe ID to a position so that when the plug is engaged in the bung hole in the top of a beer barrel, the pipe extends nearly to the bottom of the barrel. The hose 3! which is of flexible material such as rubber which allows adjustments; or a greater length of hose may be substituted therefor. After the device has been mounted upon the beer barrel the pump 2i is operated so that air is discharged into the hollow I8, down through the outlet 28, the pipe 3|, the inlet 30 and the hollow 29 into the beer barrel. The pressure within the barrel therefore raises and the beer is forced up through the pipe it), past the valve 33 when open, along the pipe l6 into the coil I4 and to the faucet I5. Refrigerant is then placed in the container l3 to cool the beer within the coil 14 and the cold beverage may be dispensed as desired.

It is a feature of this invention that the plug 26 is adjustable along the pipe 10 to change its position from the lower end. It is a further feature of this invention that the pump 2! is arranged coaxially with the bracket I! which is arranged coaxially with the pipe ill for forming a compact and solid unit. It should be recognized that the entire device is supported by the plug 26 supporting the pipe ill and for this reason it is desirable that the pump be arranged axially. A further feature lies in the arrangement wherein the pump 2| is disposed within the receptacle 13 to reduce the compass of the device and to' increase its rigidity.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
